BUTTON-MACHINE.

SPECIFICATION forming part of Letters Patent No. 396,081, dated January 15, 1889.

Application filed March 29, 1888. Serial No. 268,752. No model.) Patented in France December 10, 1886, No. 180,212, and in Belgium July 8,1887,N0. 78,153.

To aZZ whom it may concern;

Be it known that I, JAMns NATHAN Goren- DORF, Jr., a citizen of the United States of America, and at present residing at Paris, in

the Republic of France, have invented certain new and useful Improvements in Apparatus for the Mai'iufacture of Covered Buttons, (for which Letters Patent have been granted in France, No. 180,212, dated December 10,1886,

IO and in Belgium, No. 78,153, dated July 8,

1887,) of which the following is a specification.

This invention relates to improvmnents in apparatus for use in the manufacture of covered buttons.

The object of the invention is to provide a tool which will serve both for gathering inward the covering fabric and for clinching the metallic parts, whereby the fabric is secured upon the shell of the button, and also for cutting out the covering fabric.

Reference is to be had to the accompanying drawings, forming part of this specification, in which like parts are indicated by like 2 5 letters of reference in the several views, and

in which- Figure l is an elevation of the machine for covering the buttons in the position after the parts of the button have been pushed down in the mold and before being clinched. Fig.

2 is an elevation (partly in section) of the machine, the parts being shown in the position they occupy after the button is clinched. Fig. 3 is a plan, the upper part being removed. Fig. l shows a section of the combined punches and ring-cutter separately and in position for using the cutter. Fig. 5 is a cross-section (drawn on an enlarged scale) of the shell of a button before being covered.

Fig. 6 is a similar view of the entire button after the parts are clinched together. Fig. 7 is an elevation of the collet.

The metallic shell of the button is composed of a disk, (I, and a back, 1), united as shown,

4 5 the back having formed in one with it a neck, 0, in which is secured the shank (Z, formed of a disk of cloth, held in place by its edges being nipped between a and b and by a cupped metal disk, 6, having serrated edges, which penetrate the shank d and enter a correspond- 5o ing shoulder, 11, in the back h.

f is the covering fabric, stamped out in the form of a disk, secured at the back of the shell by a collet, g. This collet g is a cupped annular disk having a central aperture adapted to pass over the neck 0, and having a toothed circumference, the points of the teeth 9 being slightly convergent or directed toward the center, so that when pressed against the inwardly-turned portions of the covering fab- 6o ric f at the back Z) of the shell, as hereinafter described, they will pierce the fabric and enter the shoulder formed in the back I), and thus firmly retain the covering fabric. At the same time that the teeth g are bent inward the end of the neck 0 is splayed outward and clinched over the back of the collet g, so as to hold the collet securely in position.

The button thus constructed forms the subject of another application for Letters Patent of the United States of even date herewith, Serial No. 268,753.

The combined tool whereby the covering fabric f is gathered inward and the collet g and neck 0 are simultaneously clinched comprises a double punch, "i it, and a circular gathering hollow tool, 1, for turning inward the edges of the covering fabric in advance of the clinching action of the punches. These parts are mounted on a sliding plunger, m, guided vertically in a bracket arm or frame, the plunger being raised by a spring, m, and depressed by a cam, a, pivoted at n in the head of the bracket and operated by a lever,

72 the cam bearing directly on the head of the plunger m. The central puncha', whereby the neck cof the shell is riveted over the collet g, is preferably carried by an inner stem, e", sliding through the main plunger m, which is tubular, and is slotted at the upper part to 0 admit a small hand-lever, 2 pivoted at i on the bracket-arm, whereby the punch i maybe brought down independently of the punch 70, for the purpose of pushing the parts of the button down into proper position in the cavity of the bed-plate before the pressure is applied'for clinching them together, the punch 'i being normally held up in the plunger m by a spring, 1'". The punches i la acT, however, Together as one, The punch '1' having a shoulder, i whereby when plunger m'is depressed by The lever-cam n The? punch [willbebrought down also, and The Two punches will act concu rren Tl y.

The punch 7a is screwed on The lower end of the plunger m, so as To be readily removable and reversible T-hereon, as hereinafter described, and upon This punch 7r is TiTTed To slide The hollow gaThering-Tool l, by which The edges of The covering fal'n-ie j" (which, when pushed down along wiTh The shell in The caviTy of The bed-die, stand up against The sides of The caviTy) are forced inward Toward The center over The rear side of The back I). The punch 7; and The gaTheringaool l have inwardly-bevelcd acting faces, so as To force the Teeth of The colleT and the e( of The covering fabriein The desired direction, while The acting face of The punch i is beveled in The opposite direction and hollowed, so as To clinch The neck (7 over The back of The colleT. The hollow gaTheilug-Tool l is free To slide on The punch 7., To which iT is aTTached by studand-slot connecTions and it is carried down in advance of the punch 7;. by a spring, i confined. between The end of The Tool I and a flange, L73, on the end of The punch, This spring yielding on The gathering-Tml meeting the buTTon in The die and permiTTing The punch 7- To come down and do its work on The colleT. In one with The Tool 1 is formed an opposiTely-directed ring-cutter, 72, for eut- Ting ouTthe covering fabric. This is broughT inTo use when required by reversing The punch 7.: and gaThering-Tool l on The plunger n1. In This position (shown slmaraielyin Fig. T) The acT/ing faceol' The gathering-Tool T abnTs againsT The beveled edge of The almTinenT- shoulder "m? on The plunger m, so ThaT The pressure is Transmitted direcTly from The latter To The cutter, and The sTnds are noT strained. 13y screwing The nuT formed in The punch lctighTly upon The plunger m The punch will be raised wiThin The cuTTcr h unTil The punch also beau-s againsT The shoulder m, whereby suT'TicienT room will be provided wiThin The cutter I) for cuTT iug outthick fabrics or several Thicknesscs of fabric aT, once.

The bed-die is I'ormed in a circular plate, p, which has a number of caviTies, r, in it of dill'erent sizes, as required for buttons of different dimensions, The plate being mounTed to roTaTe abonT a ccnT-ral pillar, s, immedi aTely over The base-plate Any one of These cavities 2' may be ln-ought in line beneaThThe punch-plunger "/11, upon which a combined Tool (such as shown in Figs. 1. and 2) of corresponding diameter To The cavity is secured. In The base-plate T is liTTed a s n'ing-Tollower,

'u, The head of which rises in The caviTyof The bed-die To a suTTicienT height To form a support for The covering fabric and shell when they are firsT placed in The cavity and keep Them horizonTal while being forced down in The cavity of The bed-plate previous To The clinching nessnre being applied. The upward motion of The follower is limiTed by a stop, and on being depressed iT is n-cvented from again rising by a latch, r, acTuaTed by a spring, 1", engaging in a notch, 1", in The sTem of The follower. In This lowered posi- Tion The head of The follower is recessed in The base-plate The diskjof covering fabric having been placed over The cavity and The metal. shell havingbccn placed face downward upon iT, and The Two having been pushed down To The boTTom of The caviTy by depressing The punch 1' by means of lever T (or by hand if The punch 1 is noT independenTly nn')\'able,) The collet g is placed TeeTh downward wiThin The parallel. parT of The gathering-Tool 7, which it fits, so as To be retained Therein, and The punches i /r and gathering-Tool I. are Then brought down T'ogeTlun' by means of The cam 'n and lever /2 whereby The gaThering-Tool I, which isin advanceoli' The punches, TirsTTurns The edges of The covering fabric inward, and Then The punch 1.: forces The Teeth of The colleT/ Through said T'al'iric and clinches Them, while The punch 1 clinches The neck of The shell over The colleT, as above described. The fini sl red buTT on may Then be. ejected downward by first Turning theplaTe p partly round on its center, so as To uncover the bottom of The cavity. Upon returning The plate To position The catch 0 is released by hand and The follower allowed To rise in readiness for lllfllI- ing another buTTon.

Besides the cavities in The plate p There are beds 1c, of lead or ebonite, for The cutters 71. To cut ouT The covering fabric. upon, either of which may be bronghT inTo positionwhen The cuTTer 71. is used. The plate p is held in properposition for use by a spring laTch-bolT, .r, engaging in iTs periphery.

It is To be understood ThaT The disk (I of The shell may be either TiaT; or convex, according as a tlaT orcmlvex face buTTon is Tobe formed, The springfollow( aa being made concave accordingly; or, instead of using The follower, The caviTy maybe simply closed at bottom by The base-plaTe [,or bya removable slide liTTcd in The base-plaTe and having a eoncaved or othersin-face corresrmnding in l'orm To The face of The buTTon.

Having now pa rTicularly described and as cerlained The naTure of The said invenTion and in what manner The same is To be performed, I declare ThaT whaT I claim is- 1.
